Examples

PHP, a 64x64 JPEG avatar:

<img src="https://avi.avris.it/64/<?= strtr(base64_encode($user->getEmail()), '+/', '-_') ?>.jpg">

PHP, combine Gravatar with using Avi as a fallback:

<img src="https://www.gravatar.com/avatar/<?= md5(strtolower(trim($user->getEmail()))) ?>
        ?d=<?= urlencode('https://avi.avris.it/64/' . strtr(base64_encode($user->getEmail()), '+/', '-_') . '.jpg') ?>
        &s=64" />
